Help: Files on different server than web server

[Julia Irving]

I am trying to link to files on a shared drive that is on a different server than my web server. I wrote a program that first opens the directory and returns the filenames in a list using listfiles(). I also want to link to the files, so I thought I would use filename.getCanonicalPath() for the path. How can I specify which server and directory to use when getting the filename paths?
Thanks in advance!
